Because I'm too bored to concentrate on anything study-related and I'll do literally anything else in the hopes that it will bring back my concentration. Of course it doesn't. There is actually a word for this, SEB or study-evasive behaviour.

Just to add to KasperFeld's comment, I know we've been saying "the adverb follows the verb in main clauses" through the course, but that's for simple (non-question) sentences. It actually follows the verb and subject of the sentence. When a question is formed, only the subject and the verb are switched and adverbs remain in the same place (NB: this rule is different for subordinate clauses, where the adverb comes after the subject). For more information on word order you can refer to this PDF which should hopefully help clear things up

Normally these cases are handled automatically. Here the "you" is between the "do" and the "not" so the system didn't automatically see that "do not" = "don't", but I have manually added it as an option now
